In a 2005 paper, Changes in the Physiology of Aging during the Twentieth Century, Robert Fogel wields economic theory and statistics to not only justify a steady increase in health care spending, but also suggest that we are tending towards a healthier world because of it.

The 1993 Nobel Laureate believes that his grandchildren will live during a time when the median length of life is over 100 years.

People clearly demand [will pay for] better health care, and as long as the health care industry continues thriving as it is, Fogel believes there will be a 2 year gain in life expectancy every 10 years. Who needs Ray Kurzweil when we have economics?
